I ordered the digital edition of ME 3 from Origin. Origin does have a 'Download Manual' button for it's games, but when I used it for Mass Effect 3, it downloaded a 1.5 MB Zip file named Manuals. Inside?

There was this:

23 of those, covering a wide variety of languages.

But no manual. I like to read game manuals because I'm a nerd like that. Where is the manual for ME3? Does it even exist in a digital form?
